And you changed the oil/filter then, right? Are you using a different kind of oil than previoiusly? I always look for changes, what was different from then to now. It doesn't always help but........As AggieOlds says, Oldsmobiles do run a little lower on the oil pressure than Chevies, especially at idle. It is because the tolerances are a little looser than chevies. I have read horror stories about Oldsmobiles being rebuilt the same way chevies are with their tight clearances and then the engines fail because of that. Haven't personally experience that though, just heresay.
